These are accessed by test functions through arguments see demo

@pytest.fixture
def setup() -> None:
    print("run setup fixture before test")

@pytest.fixture
def setup_teardown() -> Iterator[None]:
    print("run setup fixture before test")
    yield
    print("run teardown fixture after test")


def test_with_fixture(setup: Callable) -> None:
    print("run test")
    assert True

def test_with_fixture_II(setup_teardown: Callable) -> None:
